God has nothing against us going to a doctor! He just doesn't want us to blindly follow them as if they were God! Blood in stools is not a good sign. At the very least, stop eating all fiber for 3 days. If the blood stops, and there is no pain, then you can be pretty sure that the fiber broke open a lesion somewhere. Definitely do NOT flush more often than every 3 weeks. Flushing is almost as challenging to the body as surgery, and you need to respect that you're asking a lot of your body every time you flush, okay? :)
